The triple substitution against Rotherham in '16/17, moving Bobby Reid from midfield into attack and requesting a towel on the sidelines...
Bristol City's Lee Johnson is not afraid to make big tactical calls and to think outside the box.
On Tuesday night up at the Riverside the 37-year-old self-proclaimed 'gunslinger' made another unorthodox decision as his team went without a substitute goalkeeper in his seven replacement players in the dugout alongside him for the game.
For some it was madness. For others, just a head coach playing the numbers.
"I think it's a game by game thing," said Johnson when we asked if he might regularly now go without a goalkeeper on the bench, at Thursday's pre-Wigan press conference.
"It's a Catch 22 really. You're damned if you do, you're damned if you don't.
"I spoke to Kenny Dalglish a number of times and he tells me that Liverpool went for a whole season once only using 13 players.
"I think that, throughout history, if you look at the history, often there is a 4-5% chance in any one game, probably less, of a goalkeeper coming on, less than 1% coming on maybe even," explained the head coach, referring to one of his mentors in the game.
So what would have happened if Aden Flint had stamped on Max O'Leary's foot - accidentally - instead of Andi Weimann's on Tuesday night and a substitution for the goalkeeper had been needed?
"The thing is that we have got some players who are not bad in goal as well because if we are going to make that decision, I won't tell you who, but if we are going to make that decision not to have a goalkeeper you need to know that somebody decent can go in there.
"We have some players who started their careers as kids in goal. That'll be an interesting little research project for you," teased Johnson.
The 'research project' took a whole three minutes as Bristol City club captain Bailey Wright was next to speak at the media call and we immediately asked the skipper which outfield players were handy with their, erm, hands...
"We've got a few lads - Tomas Kalas would probably put his hand up and say he'd play in goal," explained the 26-year-old right-back or centre-back on who may have gone in the nets if needed on Tuesday night.
"I don't know if anyone knows but he was a goalkeeper until he was about 13. There's a little fun fact for you. His coach then told him that he was too fast to be a goalkeeper - can you believe that?
"Obviously, it's one of those things: the gaffer made the decision [not to have a goalkeeper on the bench] and you don't really think about to be honest.
Lee Johnson is maturing into one of the best coaches - and win over Wigan helps cement it
"You're just out there to play the game and win the game. If anything like that was ever to come about, then we would obviously just deal with it then. It was what it was and I'm sure there would be somebody who would be willing to step in for the good of the team and do it if need be."
Bristol City play Wigan Athletic at 3pm on Saturday.
